Quran, Mutawatir?

As it is commonly said that "Quran is mutawatir". Question: -- I just want to know, is there anyone from the Salaf who has said "Quran is mutawatir" ?? I mean, the word "Mutawatir" was used by anyone in the first 3 generations of Islam? Please notice, I am not saying to prove to me how Quran is mutawatir! If there was someone who said it, just give me authentic evidence! If not, please tell me, "no, there was none". Thank You.
